Based on past threads, I believe the best way to deactivate enterprise activation is to 'wipe handheld'. I want to know if I do that, how do I restore my contacts.
My contacts are the only piece of information I care about on the device. I have a Blackberry 9700 activated on BES.

As a BES Admin, I can tell you that you will not be able to restore the wireless sync items to your device after you've wiped it. Contacts, Calendar, etc will be greyed out.

This is not true. You can backup the data fine even if it is activated on the BES. You cannot restore certain databases when the device is activated on the BES. As you said, they're grayed out.

There's a way around that as well. Delete the Desktop [SYNC] service book. Then all the items will be available. Once you restore, then undelete the service book or resend it from the server.

If the device has been wiped, there shouldn't be any issue restoring the data.
